Try putting a bottle of redline fuel additive in your next tank. You can find it on amazon for ten bucks or so a bottle.

When you notice a 100% improvement, change out your injectors for a good lasting repair.

Also, do you have a mity vac? If not, does your dash have an economy gauge? Vacuum leaks will cause rough idle/ stalling.
